.To all whom it may concern:

' Be it known that I, JOSEPH W. SoHLoss, a citizen of the United States,residing at the city of New York, in the borough of Manhattan and Stateof New York, have invented certain new and usefulImprovements inFeatherbone-Making Apparatus, of which the following is a full, clear,and exact description. 7

My invention relates to the manufacture of featherbone, and particularlyto appara-' tus for completing the manufacture after the quills havebeen bundled together into a strip and wound in the usual manner. As iswell known, the treatment of the strip in completing the manufactureentails three operations, first the sizing or subjecting the strip to abath in a glutinous fluid, second, the drying of the sized strip, andfinally, the rolling and compressing of the dried strip into its finalform.

A general object of my invention is to provide an apparatus for this.purpose which will be simpler and more compact than those in generaluse, and which will be more. reliable in its operation. In the formheretofore used the apparatus has a sizing tank through which the stripis guided in a generally horizontal direction,

and a heated drying box having a slit in one end through which the sizedstrip enters after the surplus glue is removed, and having two powerdriven rollers over which the strip passes back and forth horizontallyuntil dried, and a rolling machine outside the box through which thedried strip passes after it comes from the box. L machine is commonlyprovided with'heated The rolling rollers between which the strip passesand is heated asfit is compressed.

The passage of the strip through the air after it emerges from thedrying box, when it is momentarily more or less cooled, and then thesudden subjection of it to therelatively great heat of the rollingmachine, frequently deleteriously affects the strip, ren-'v dering itbrittle, and an object ofmy invention is to obviate this disadvantage.

I have found that a superior product can be obtained if the strip isrolled while still at the temperature of the drying box before it ispermitted to undergo any change in temperature, and I have further foundthat if this is done the heating may be dispensed with during therolling operation. In accordance with my invention, therefore, I

place the rollers of the rolling device inside the drying box inposition, 'to receive the dr ed strip as it comes off the'drum, and thedriv ng means for the rollers are preferably outsldethe box andconnected to the driving means for the drum so that the drum and rollersare driven at the same peripheral speed. In addition to rendering thedevice more compact and dispensing with heatmg means for the rollingmachine, this 'construction has the advantage of producing a moreunlform and resil ent article.

Ishall now describe the embodimentsof my'invention illustrated in theaccompanying drawings, and shall thereafter point-out my invention inclaims.

Figure 1 is a side elevation of a complete apparatus embodying myinvention. "Fig. 2 1s afront elevation of the same with the reel removedand a portion of the frontof the drying box broken away. Fig.3 is avertical sectional elevation, the section through the drying boxbeing'taken on line of Fig. 2, and the section through the sizing tankbeing taken on line 3--3 of Fig. 2." i L Th'esizingtank comprises anopenreceptacle 1. in which the sizing fluid is contained, the flanged endsof which rest upon a tank 2 which contains heatedwater.. The water ispoured in through a stand pipe 3 which communicates with a pipe 4entering the tank,

the height of the water in the tank being indicated by its. heightin'the stand pipe 3. In order to heat the watenin the tank 2, twoperforated gas pipes ,5 are provided un .derneath the tank which connectwith the common pipeG communicating through pipe 7 with the gasmain 8,suitable cocks being provided 1n the pipes 5 to control the flow of gas.A door 2 affords access "to the nclosed gas pipes 5 underneaththe tank 2.A frame 9 rests. upon the sidesof'thereceptacle 1, being securedthereto by thumbscrews 10, and has three guide-rollers '11 disposed inthesi'zing fluid, underwhich the strip 12 passes and is thereby guidedthrough the sizing bath.

In order to remove any surplus glue from the material after passingthrough the bath,

the strip passes through 'a-suitable device.

such as a wringer, disposed [on the; sizing tank and. in the formshownhaving two a rubber rollers 13, the lower roller being mounted 1nstationary bearings and the upper roller being mounted in, bearing Afterpassing through the wringer, the

sized strip enters the drying box 15 through a slit not shown in itsfront wall near the lower end at its right side. The drying box is what1 term an upright box, being considerably elongated and standing on endwith its longest sides vertical, and is located adjacent the sizingtank. Two horizontal arallel drums extending substantially the fullwidth of the drying box are journaled in bearings on the sides of thedrying box, one above the other, the lower drum 16 being disposed nearthe bottom, and the upper drum. 1'? being disposed near the top of thedrying box. The lower drum 16 is power driven being provided on the leftend of its shaft outside the drying box with a pulley 18 which may bedriven by a belt or in any other suitable way. The upper drum 1'? mayalso be power driven but generally this is unnecessary.

The sized strip after entering the drying box is passed successively andcontinuously around the two drums, as shown, two suitable guidemembers19 being provided, one near "each drum, which are attached at their endsto the sides of the drying box and have a plurality of fingers extendingin the path of the strip and properly spacing the several I turns.

In order to remove'any glue from the drum 16 which may have beentransferred to its surface from the freshly sized strip, a scraper 20 isprovided which extends the length of the drum 16 and rests upon itsperiphery at such an angle as to scrape off the glue; This scraper 20 isattached to a transverse rock-shaft 21 journaled in the sides of thedrying box, and a weighted -lever-arm 22 is attached to the r0ck-shaftso that its weight serves to yieldingly hold the scraper 20 against thesurface of the drum 16.

p In order to supply heat to the drying box to dry the strip of materialas it is rotated over the drums, a stand pipe 23 is provided along thevertical side of the drying box opposite the side at which the freshlysized strip enters. inner side perforated, as shown in Fig. 3, andcommunicates at its lower end with a pipe 24 leading from a gas heater25. Air is drawn into this heater by a fan26, and this air is heated byburning gas emer ing from a plurality of perforated pipes 2 at thebottom of the heater which communicate with the gas main 8, as shown inFig. 2. It is apparent that the heated air will pass through theupwardly-inclined pipe 24 and into the stand pipe 23 and thence throughThis stand pipe 23 has its the perforations into the drying box, thisnatural circulation being assisted by the fan '26. It will be noted thatthe strip as it dries approaches the stand pipe 23 in its passage aroundthe drums, and it is therefore subjected to increasing heat as it driesout and its thorough drying is thereby assured.

After the drying operation is completed and the strip comes 05 from thedrum 16, J

passing through a slot provided for this purpose in the scraper 20, asshown in Fig. 3, it enters the rolling machine and is rolled andcompressed before it passes out of the drying box, thereby finishing thearticle without subjecting it to any sudden changes in temperature. Therollers 28 and 29 of the rolling machine are mounted upon the inner endsof two parallel shafts 30 and 31 which extendhorizontally into thedrying box in front of the lower drum 16 at the end from which the driedstrip passes ed the drum, and these shafts bear in frames 32 and 33outside of the drying box which are supported upon a bracket 3d on theside of the box. The lower shaft 31 is mounted in stationary bearingsand the upper shaft 30 is mounted in vertically-adjustable bear- 'i-ngblocks, the vertical position of which is controlled by adjusting screws35, suitable locking nuts 36 being provided to lock the screws inadjusted position. By these means the roller 28 may be made to approachits complementary roller, more or less, and the compression upon thedried strip be thereby adjusted.

The roller 28 has a circumferential tongue which fits into acomplementarygroove in the periphery of the roller 29, and the driedstrip as it comes off the drum 16 is passed through the groove in theroller 29 and is compressed andshaped. It is apparent that the tongueand groove may have either transversely flat or curved engagingsurfaces, as is desired.

The rollers 28 and 29 are driven in opposite directions, by intermeshingpinions 37 on the shafts 30 and 31, the lower shaft 31 being driven fromthe drum 16 by a sprocket chain 38 which passes around a sprocket wheel39 on the end of theshaft 31 and around a sprocket wheel 40 on the-endof the drum shaft. Thesprocket wheel-s 39 and 10 are so proportioned insize, that the rollers 28 and 29 are driven at the same rate, that is,at thesame peripheral speed as the drum 16, and the tension upon thestrip as it passes through the rolling machine is therefore the same asit is when passing over the drums.

After passing through the rolling machine, the finished. strip emergesfrom the drying box through a slit 41 in front of the box, and fromthence to a suitable reel 42 on which it is wound, the reel being drivenby a belt 43 which passes around a pulley 44 on the shaft 30 and over apulley 45 on the reel, the friction of the belt being such that it willslip as the size of the roll of featherbone increases on the reel, andwill therefore at all times rotate the reel just fast enough to Wind upthe finished strip.

The drying box is provided on its front with hinged doors 456 which meetat the middle and are provided with suitable locking means, and whichextend from the top well down toward the bottom of the box, the lowerpart of the front being provided with a removable portion 47 secured inplace by slide bolts, in the usual Way, thus the front of the drying boxcan be opened and access readily had to its interior.

It is obvious that various modifications may be made in the constructionshown in the drawings and above particularly described, within theprinciple andscope of my invention. I

I claim p 1. Featherbone making apparatus comprising a drying boxprovided With a source of heat, a plurality of drums rotatively mountedtherein and arranged to receive and convey a continuous strip of sizedmaterial passed successively around them, a rolling device disposedwithin the drying box and arranged to receive the dried strip as itcomes from the drums, and means for driving one of the said drums andthe rolling device at the same rate.
